A new ligand (L), 6-mono-(2-(2-hydroxy-3-(hydroxymethyl)-5-methyl benzylamino)- ethylamino)-β-cyclodextrin, based on β-cyclodextrin derivatives with dinucleating units was synthesized and used to prepare a trimetallic bis-ligands zinc complex (Zn3 (L2−) 2). The esterase activity of the complex was investigated by the hydrolysis of two carboxylic acid esters, bis (4-nitrophenyl) carbonate (BNPC) and 4-nitrophenyl acetate (NA), and a DNA ...
